I have a 93 chevy C2500 3/4 ton and I need to know how much can I pull via goose neck I had the goose neck ball and receiver installed in my truck a couple days ago because I work for a transporting company there are no engine problems and the tranny is a 4L80E and it is brand new as of yesterday the vehicle has a GVW of 8600 lbs so whats the max load I can pull with my truck (in pounds) without tearing it up badly?
